Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present application more clear, the embodiments of the present application will be further described in detail with reference to the accompanying drawings.
Before explaining the power supply method and system of the AR-HUD system provided in the embodiment of the present application in detail, an application scenario provided in the embodiment of the present application is explained first.
With the continuous development of society, automobiles become indispensable transportation means in daily life of people, the accompanying traffic safety problem becomes more serious, and traffic accidents become the first killer of lives and properties of people in the current society. Therefore, automobile safety is becoming a major direction for future automobile development. The AR-HUD system is an automobile auxiliary vision safe driving system, and the system projects some important information required by a driver when driving to the windshield glass of an automobile through the light path of the AR-HUD system, so that the driver does not need to look down at the instrument panel, eyes always look at the front field road surface, and the influence of head lowering on safe driving is reduced. However, as the number of electric appliances on the automobile increases, the power supply of the power supply system of the whole automobile is unbalanced, so that the voltage of the whole automobile is low, certain electric appliances cannot work, the virtual image display of the AR-HUD system is affected, and hidden dangers are brought to the driving safety and the comfort.
Based on the application scene, the embodiment of the application provides a power supply method and system of an AR-HUD system, and the power supply safety and reliability are improved.
Fig. 1 is a schematic structural diagram of a power supply system of an AR-HUD system according to an embodiment of the present application, and referring to fig. 1, the power supply system is installed in an automobile, and the power supply system includes a first storage battery 1, a second storage battery 2, a backup power supply 3, and a power supply controller 4; the power supply controller 4 is respectively connected with the first storage battery 1, the second storage battery 2 and the standby power supply 3; the first battery 1 is a battery that solely supplies power to the AR-HUD system 5 in the automobile, the second battery 2 is a battery that supplies power to electrical appliances in the automobile, and the backup power supply 3 is used to charge the first battery 1 and the second battery 2.
In the embodiment of the application, because the backup power supply is arranged in the automobile and can charge the first storage battery, when the electric quantity of the first storage battery is not enough to support the AR-HUD system of the automobile, the backup power supply can charge the first storage battery, so that the first storage battery meets the electric quantity requirement for supplying power to the AR-HUD system, the condition that the display state of the AR-HUD system is unstable due to too low electric quantity is improved, and the driving safety and the driving comfort are further improved.
It should be noted that first battery 1 is a battery that solely supplies power to the AR-HUD system in the automobile, that is, first battery 1 is a self-contained small battery of the AR-HUD system and is dedicated to supplying power to the AR-HUD system. The second battery is a battery for supplying power to electric appliances in the vehicle, that is, the second battery 2 is a battery for supplying power to other electric appliances in the vehicle other than the AR-HUD system.
In some embodiments, the power controller 4 can obtain the state of charge of the first battery 1, the second battery 2 and the backup power source 3 in the automobile; when the first storage battery 1 is smaller than the electric quantity threshold value, the power controller 4 can process the first storage battery 1 according to the electric quantity states of the second storage battery 2 and the standby power supply 3, and supply power to the AR-HUD system 5 through the first storage battery 1.
As an example, when the amount of power of the first storage battery 1 is less than the power threshold and the amount of power of the backup power supply 3 is greater than or equal to the power threshold, the power controller 4 can control the backup power supply 3 to charge the first storage battery 1; and when the electric quantity of the first storage battery 1 and the electric quantity of the standby power supply 3 are smaller than the electric quantity threshold value and the electric quantity of the second storage battery 2 is larger than or equal to the electric quantity threshold value, controlling the second storage battery 2 to charge the first storage battery.
Since the electric quantity of the first battery 1 may be insufficient to power the AR-HUD system 5 when the electric quantity of the first battery 1 is smaller than the electric quantity threshold, the AR-HUD system 5 may be unstable in display under such a situation, and therefore, the first battery 1 needs to be charged in time. When the first storage battery 1 is charged, when the electric quantity of the standby power supply 3 is greater than or equal to the electric quantity threshold value, the power supply controller 4 can control the standby power supply 3 to charge the first storage battery 1; when the capacity of the backup power supply 3 is less than the capacity threshold and the capacity of the second storage battery 2 is greater than or equal to the capacity threshold, the power supply controller 4 can control the second storage battery 2 to charge the first storage battery.
It should be noted that, in the case where the first storage battery 1 is smaller than the electric quantity threshold and the electric quantity of the backup power supply 3 is greater than or equal to the electric quantity threshold, the case where the electric quantity of the backup power supply 3 is greater than or equal to the electric quantity threshold includes the case where the electric quantities of the backup power supply 3 and the second storage battery 2 are both greater than or equal to the electric quantity threshold, and the electric quantity of the backup power supply 3 is greater than or equal to the electric quantity threshold and the electric quantity of the second storage battery 2 is smaller than the electric quantity. When the electric quantity of the standby power supply 3 and the electric quantity of the second storage battery 2 are both greater than or equal to the electric quantity threshold value, the power supply controller 4 preferentially selects the standby power supply 3 to charge the first storage battery 1, or the power supply controller 4 can also charge the first storage battery through either the standby power supply 3 or the second storage battery 2.
It should be noted that the power threshold can be set in advance according to the requirement, for example, the power threshold can be 20 ma hours, 10 ma hours, and the like.
In some embodiments, the electric quantities of the first storage battery 1, the second storage battery 2 and the backup power supply 3 may all be less than the electric quantity threshold, and at this time, the virtual image of the AR-HUD system 5 can display electric quantity alarm information.
Because when first battery 1, second battery 2 and stand-by power supply 3's electric quantity all was less than the electric quantity threshold value, power controller 4 can't charge first battery 1 through second battery 2 and stand-by power supply 3, consequently, AR-HUD system 5 can directly show electric quantity alarm information on the virtual image to indicate that the driver electric quantity is not enough.
In some embodiments, the charge of the first battery 1 may be greater than or equal to the charge threshold, and at this time, the first battery 1 does not need to be charged by the second battery 2 or the backup power source 3, and the first battery 1 can directly power the AR-HUD system 5.
In some embodiments, the power controller 4 can charge the second storage battery 2 through the backup power source 3 when the power of the first storage battery 1 and the backup power source 3 may be greater than or equal to the power threshold and the power of the second storage battery is less than the power threshold.
Referring to fig. 1, the backup power source 3 includes a wind power source 31 and/or a solar power source 32.
In some embodiments, the backup power source 3 can also be other power sources, for example, other storage batteries, etc.
As an example, when the power of any one of the wind power source 31 and the solar power source 32 is greater than or equal to the power threshold, if the first storage battery 1 or the second storage battery 2 needs to be charged, the power controller 4 can control at least one of the wind power source 31 and the solar power source 32 to charge the first storage battery 1 or the second storage battery 2. When the electric quantity of only one of the wind power source 31 and the solar power source 32 is greater than or equal to the electric quantity threshold value, and the first storage battery 1 or the second storage battery 2 needs to be charged, the power controller 4 controls the power source with the electric quantity greater than or equal to the electric quantity threshold value to charge the first storage battery 1 or the second storage battery 2. When the electric quantities of the wind energy power supply 31 and the solar energy power supply 32 are both smaller than the electric quantity threshold value, it is determined that the electric quantity of the standby power supply 3 is smaller than the threshold value, and the first storage battery 1 or the second storage battery 2 cannot be charged through the standby power supply 3.
Referring to fig. 1, the wind energy power source includes a wind energy generator 311, a wind energy controller 312, and a wind energy super capacitor 313; the wind energy generator 311 is connected with the wind energy controller 312, the wind energy controller 312 is connected with the wind energy super capacitor 313, and the wind energy super capacitor 313 is connected with the power controller 4.
As an example, the wind power generator 311 is disposed at a tail portion of a vehicle, and generates power by crosswind of the vehicle during driving; wind energy controller 312 is used to convert the electricity generated by wind energy generator 311 into electricity that can be stored in wind energy super capacitor 313; the wind energy super capacitor 313 is used to store electricity generated by the wind energy generator 311.
It should be noted that, when the power controller 4 controls the wind energy power supply to charge the first storage battery 1 or the second storage battery 2, the wind energy super capacitor 313 is controlled to transmit the electric power generated by the wind energy generator 311 to the first storage battery 1 or the second storage battery 2.
Referring to fig. 1, the solar power supply 32 includes a solar panel 321, a photovoltaic controller 322, and a solar super capacitor 323; the solar cell panel 321 is connected with the photovoltaic controller 322, the photovoltaic controller 322 is connected with the solar super capacitor 323, and the solar super capacitor 323 is connected with the power controller 4.
As an example, a solar cell panel 321 is disposed at a roof portion of an automobile, and the solar cell panel 321 is used to convert solar energy into electricity; the photovoltaic controller 322 is configured to convert electricity generated by the solar panel 321 through illumination into electricity that can be stored in the solar super capacitor 323; the solar super capacitor 323 is used to store electricity generated by the solar cell panel 321 through illumination.
When the power controller 4 controls the solar power source 32 to charge the first storage battery 1 or the second storage battery 2, the solar super capacitor 323 is controlled to transmit the electric power generated by the solar panel 321 to the first storage battery 1 or the second storage battery 2.
It should be further noted that the wind energy super capacitor 313 and the solar energy super capacitor 323 are super capacitors, which are power sources with special performance between the conventional capacitor and the battery, and mainly store electric energy by electric double layers and redox pseudo-capacitor charges. However, no chemical reaction occurs during the energy storage process, which is reversible, and since the super capacitor can be repeatedly charged and discharged tens of thousands of times, the solar super capacitor 323 temporarily stores the electric energy generated by the solar cell panel 321 and processed by the photovoltaic controller 322. Wind energy super capacitor 313 functions to temporarily store electrical energy generated by wind energy generator 311 and processed by wind energy controller 312.
In some embodiments, when the power of the first battery 1 is less than the power threshold, and the solar panel 321 cannot receive light and cannot generate enough power, and the wind power generator 311 cannot generate power, the power controller 4 can transmit the power of the second battery 2 to the first battery 1 when the power of the second battery 2 is greater than or equal to the power threshold, so as to supply power to the AR-HUD system through the first battery 1.
In the embodiment of the application, because the backup power supply is arranged in the automobile and can charge the first storage battery, when the electric quantity of the first storage battery is not enough to support the AR-HUD system of the automobile, the backup power supply can charge the first storage battery, so that the first storage battery meets the electric quantity requirement for supplying power to the AR-HUD system, the condition that the display state of the AR-HUD system is unstable due to too low electric quantity is improved, and the driving safety and the driving comfort are further improved.
Fig. 2 is a flowchart of a power supply method of an AR-HUD system according to an embodiment of the present disclosure, where the power supply method of the AR-HUD system may include the following steps:
step 201: the electric quantity state of first battery, second battery and stand-by power supply in the car is acquireed, and this first battery is the battery of the augmented reality new line display AR-HUD system power supply in this car alone, and this second battery is for the battery that supplies power for the electrical apparatus in this car, and this stand-by power supply is used for charging this first battery and this second battery.
Step 202: and when the first storage battery is smaller than the electric quantity threshold value, processing the first storage battery according to the electric quantity states of the second storage battery and the standby power supply.
Step 203: after the first battery is charged, the AR-HUD system is powered by the first battery.
In the embodiment of the application, when the electric quantity of the first storage battery which supplies power for the AR-HUD system independently is lower, the first storage battery can be charged according to the electric quantity states of the standby power supply and the second storage battery which supplies power for the electric appliances in the automobile, so that the first storage battery meets the electric quantity requirement for supplying power for the AR-HUD system, the condition that the display state of the AR-HUD system is unstable due to too low electric quantity is improved, and the driving safety and the driving comfort are further improved.
In some embodiments, when the first battery is less than the charge threshold, processing the first battery according to the charge states of the second battery and the backup power source includes:
when the electric quantity of the first storage battery is smaller than the electric quantity threshold value and the electric quantity of the standby power supply is larger than or equal to the electric quantity threshold value, controlling the standby power supply to charge the first storage battery;
and when the electric quantity of the first storage battery and the electric quantity of the standby power supply are smaller than the electric quantity threshold value and the electric quantity of the second storage battery is larger than or equal to the electric quantity threshold value, controlling the second storage battery to charge the first storage battery.
In some embodiments, after obtaining the state of charge of the first battery, the second battery and the backup power source in the automobile, the method further comprises:
when the electric quantity of this first battery, this second battery and this stand-by power all is less than the electric quantity threshold value, show electric quantity alarm information on the virtual image of this AR-HUD system.
In some embodiments, after obtaining the state of charge of the first battery, the second battery and the backup power source in the automobile, the method further comprises:
when the electric quantity of the first storage battery and the standby power supply is larger than or equal to the electric quantity threshold value and the electric quantity of the second storage battery is smaller than the electric quantity threshold value, the second storage battery is charged through the standby power supply.
All the above optional technical solutions can be combined arbitrarily to form an optional embodiment of the present application, and the present application embodiment is not described in detail again.
Fig. 3 is a flowchart of a power supply method of an AR-HUD system according to an embodiment of the present disclosure, which is illustrated in the embodiment that the power supply method of the AR-HUD system is applied to an automobile, and the power supply method of the AR-HUD system may include the following steps:
step 301: the automobile acquires the electric quantity states of the first storage battery, the second storage battery and the standby power supply.
It should be noted that the first storage battery is a storage battery which solely supplies power to an AR-HUD system in an automobile, the second storage battery is a storage battery which supplies power to electric appliances in the automobile, and the backup power supply is used for charging the first storage battery and the second storage battery. That is, the first battery is a self-contained small battery of the AR-HUD system and is specially used for supplying power to the AR-HUD system, and the second battery is a battery for supplying power to other electric appliances in the automobile except the AR-HUD system.
Since the first battery is a battery that supplies power to the AR-HUD system in the automobile alone, the virtual image display of the AR-HUD system may be affected when the electric quantity of the first battery is low, and therefore, the automobile needs to monitor the electric quantity of the first battery. The second storage battery needs to supply power to the electric appliances in the automobile, and the standby power supply can charge the first storage battery and the second storage battery, so that the automobile also needs to monitor the second storage battery and the standby power supply.
As an example, the automobile can monitor and acquire the power states of the first storage battery, the second storage battery and the backup power supply in real time, and also can monitor and acquire the power states of the first storage battery, the second storage battery and the backup power supply at specified time intervals, and also can monitor and acquire the power states of the first storage battery, the second storage battery and the backup power supply when receiving the acquisition instruction, and also can monitor and acquire the power states of the first storage battery, the second storage battery and the backup power supply after the automobile is started, and also can monitor and acquire the power states of the first storage battery, the second storage battery and the backup power supply after the AR-HUD system is started.
It should be noted that the specified time interval can be set in advance according to the requirement, for example, the specified time interval can be 1 hour, 3 hours, 6 hours, and so on. The acquisition instruction can be triggered when a driver acts on a virtual switch or a hardware switch of the automobile through specified operation, and the specified operation can be click operation, sliding operation, toggle operation, pressing operation, voice operation and the like.
In some embodiments, the state of charge of the first battery, the second battery, and the backup power source obtained by the vehicle can include a plurality of conditions, for example, the electric quantities of the first battery, the second battery, and the backup power source are all less than the electric quantity threshold value, or the electric quantity of the first battery is less than the electric quantity threshold value and the electric quantities of the second battery and the backup power source are all greater than or equal to the electric quantity threshold value, or the electric quantities of the first battery and the backup power source are all less than the electric quantity threshold value and the electric quantity of the second battery is greater than or equal to the electric quantity threshold value, or the electric quantities of the first battery, the second battery, and the backup power source are all less than the electric quantity threshold value and the electric quantity of the backup power source is less than the electric quantity threshold value, alternatively, the charge of the first battery and the backup power source is greater than or equal to the charge threshold and the charge of the second battery is less than the charge threshold, and so on.
It should be noted that the power threshold can be set in advance according to the requirement, for example, the power threshold can be 20 ma hours, 10 ma hours, and the like.
In some embodiments, the power supply mode of the automobile is different according to different electric quantity states of the first storage battery, the second storage battery and the standby power supply.
As one example, the AR-HUD system is powered by the first battery when the charge of the first battery is greater than or equal to a charge threshold.
Since the first battery is a battery that supplies power to the AR-HUD system in the automobile alone, the first battery can supply power to the AR-HUD system as long as the electric quantity of the first battery is sufficient.
As one example, when the charge of the first battery and the backup power source is greater than or equal to a charge threshold and the charge of the second battery is less than the charge threshold, the second battery is charged by the backup power source.
Because the first battery can supply power to the AR-HUD system when the electric quantity of the first battery is greater than or equal to the electric quantity threshold value, the first battery does not need the standby power supply to supply power at the moment, and therefore when the electric quantity of the standby power supply is sufficient and the electric quantity of the second battery is less than the electric quantity threshold value, the standby power supply charges the second battery.
It is worth explaining that, when the electric quantity of the second storage battery is smaller than the electric quantity threshold value and the electric quantity of the standby power supply is larger than or equal to the electric quantity threshold value, the standby power supply charges the second storage battery under the condition that the first storage battery is not required to be charged, so that the maximum utilization of resources is ensured, and the electric energy of the whole vehicle is saved.
In some embodiments, the first battery AR-HUD system supplies power when the charge of the first battery is greater than or equal to the charge threshold and the charge of the second battery and the backup power source are both less than the charge threshold, and the first battery does not charge the second battery and the backup power source.
In some embodiments, when the electric quantity of the first storage battery and the electric quantity of the second storage battery are both greater than or equal to the electric quantity threshold value and the electric quantity of the standby power supply is less than the electric quantity threshold value, the first storage battery AR-HUD system supplies power, the second storage battery supplies power to other electric appliances in the automobile, and the first storage battery and the second storage battery do not charge the standby power supply.
In some embodiments, when the first battery is less than the threshold amount of charge, it indicates that the first battery cannot supply power to the AR-HUD system of the vehicle through its own electric power, and the vehicle can perform the following operation of step 302.
Step 302: and when the first storage battery is smaller than the electric quantity threshold value, the automobile processes the first storage battery according to the electric quantity states of the second storage battery and the standby power supply.
Since the handling of the first battery by the vehicle depends on the electrical quantities of the second battery and the backup power supply when the first battery is less than the electrical quantity threshold, the vehicle needs to handle the first battery according to the electrical quantity states of the second battery and the backup power supply of the vehicle.
As an example, when the first storage battery is smaller than the charge threshold, the operation of the vehicle to process the first storage battery according to the charge state of the second storage battery and the backup power supply comprises: when the electric quantity of the first storage battery is smaller than the electric quantity threshold value and the electric quantity of the standby power supply is larger than or equal to the electric quantity threshold value, controlling the standby power supply to charge the first storage battery; and when the electric quantity of the first storage battery and the electric quantity of the standby power supply are smaller than the electric quantity threshold value and the electric quantity of the second storage battery is larger than or equal to the electric quantity threshold value, controlling the second storage battery to charge the first storage battery.
Since the electric quantity of the first storage battery is less than the electric quantity threshold value, which indicates that the electric quantity of the first storage battery may not be enough to supply power to the AR-HUD system, the AR-HUD system may have unstable display under such a condition, and therefore, the first storage battery needs to be charged in time.
It should be noted that, in the case where the first storage battery is less than the electric quantity threshold and the electric quantity of the backup power supply is greater than or equal to the electric quantity threshold, the case where the electric quantity of the backup power supply is greater than or equal to the electric quantity threshold includes the case where both the electric quantities of the backup power supply and the second storage battery are greater than or equal to the electric quantity threshold, and the case where the electric quantity of the backup power supply is greater than or equal to the electric quantity threshold and the electric quantity of the second storage battery is less than the electric quantity threshold. When the electric quantity of the standby power supply and the electric quantity of the second storage battery are both larger than or equal to the electric quantity threshold value, the automobile can preferentially select the standby power supply to charge the first storage battery, or the automobile can also charge the first storage battery through any one of the standby power supply or the second storage battery.
In some embodiments, when the electric quantity of the first storage battery and the electric quantity of the second storage battery are both less than the electric quantity threshold value, and the electric quantity of the backup power supply is greater than or equal to the electric quantity threshold value, the backup power supply can charge the first storage battery, and if the electric quantity of the backup power supply is still greater than the electric quantity threshold value and the electric quantity of the second storage battery is less than the electric quantity threshold value, the backup power supply can further continue to charge the second storage battery.
As an example, when the power of the first storage battery, the second storage battery and the standby power supply are all smaller than a power threshold value, power alarm information is displayed on a virtual image of the AR-HUD system.
Because when first battery, second battery and stand-by power supply's electric quantity all was less than the electric quantity threshold value, it is lower to explain the whole electric quantity of car, and arbitrary power can't carry out sufficient power supply to the car, consequently, the car can show electric quantity alarm information on the virtual image of AR-HUD system to indicate that the driver electric quantity is not enough.
In some embodiments, after the automobile displays the electric quantity alarm information on the virtual image of the AR-HUD system, the AR-HUD system of the automobile can be turned off after a specified time.
Therefore, the standby power supply comprises a wind energy power supply and/or a solar energy power supply, the wind energy power supply comprises a wind energy generator, a wind energy controller and a wind energy super capacitor, the solar energy power supply comprises a solar cell panel, a photovoltaic controller and a solar energy super capacitor, and the wind energy super capacitor and the solar energy super capacitor are super capacitors, so that the electric quantity of the standby power supply refers to the electric quantity of the wind energy super capacitor and/or the solar energy super capacitor.
As an example, when the power of any one of the wind power source and the solar power source is greater than or equal to the power threshold, if the first storage battery or the second storage battery needs to be charged, the vehicle can control at least one of the wind power source and the solar power source to charge the first storage battery or the second storage battery. When the electric quantity of only one of the wind power supply and the solar power supply is larger than or equal to the electric quantity threshold value, the automobile can control the power supply with the electric quantity larger than or equal to the electric quantity threshold value to charge the first storage battery or the second storage battery when the first storage battery or the second storage battery needs to be charged. When the electric quantity of the wind energy power supply and the electric quantity of the solar energy power supply are both smaller than the electric quantity threshold value, the electric quantity of the standby power supply is determined to be smaller than the threshold value, and the first storage battery or the second storage battery cannot be charged through the standby power supply.
Step 303: after the first storage battery is charged, the automobile supplies power to the AR-HUD system through the first storage battery.
When the first storage battery is smaller than the electric quantity threshold value, under the condition that the electric quantity of the standby power supply or the second storage battery is sufficient, the first storage battery can be charged through the standby power supply or the second storage battery, therefore, the first storage battery cannot be powered off, and the automobile can still supply power for the AR-HUD system through the first storage battery.
In the embodiment of the application, when the electric quantity of the first storage battery supplying power for the AR-HUD system is low, the automobile can charge the first storage battery according to the electric quantity states of the standby power supply and the second storage battery supplying power for the electric appliances in the automobile, so that the electric quantity requirement for supplying power to the AR-HUD system is met by the first storage battery, the condition that the display state of the AR-HUD system is unstable due to too low electric quantity is improved, and the driving safety and the driving comfort are improved. Simultaneously, because stand-by power supply can also charge to the second battery under the condition that the second battery electric quantity is lower and do not charge to first battery, guaranteed resource maximize and utilized, practiced thrift whole car electric energy.
